I've had my Monstera deliciosa for about eight months now and I'm finally seeing fenestration on the new leaves

I've had my Monstera deliciosa for about eight months now and I'm finally seeing fenestration on the new leaves! I was starting to worry it wasn't getting enough light, but I moved it closer to my east-facing window a few months back and that seems to have done the trick. The leaves are still smaller than I'd like, but I'm not complaining. Does anyone else find that their Monstera grows way faster during certain seasons? Mine barely budged during the dry season here.
